The PS-010 is an on/off wall switch and slide dimmer used for 0-10VDC fluorescent dimming ballasts. When used as a stand-alone device, the slide control provides flicker-free dimming of between 100% and 5% of lamp output. It also provides a selection of 120VAC or 277VAC in either a single-pole or 3-way devices. Current limit is 8.5 amps at 120VAC and 3.7 amps at 277VAC (approximately 1,000 watts). The PS-010 then allows manual dimming for lights in the room when lower light levels are desired.
